What this shows Nanjing's Innovation Score is 66.9/100 (top 1% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Nanjing?

Each dot is one of Nanjing’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Nanjing’s own 8.0 claims/patent is at or below the 15.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

How Nanjing's grant cadence moved

Between 2020–2024, Nanjing University of Aeronautics and Astronautics received 103 grants versus 3 in 2015–2019 (+3333% equal-window velocity, top decile growth). Across complete PatentsView years, output peaked in 2023 at 38 grants and bottomed in 2018 at 1. Lead class G06T accounts for 19.4% of the portfolio across 101 subclasses. Volume neighbours: Keihin Corporation (#2,773) and Avigilon Corporation (#2,781).

Nanjing's three-year grant acceleration

Nanjing University of Aeronautics and Astronautics shows 92 grants in 2022–2024 against only 13 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
